A Monograph Of The Geometrid Moths Or Phalaenidae Of The United States PDF Download

The Phalaenidae are a family of great extent. There are eight hundred species of the family enumerated in Staudinger and Wocke's Catalogue of the Lepidoptera of Europe. In the present work, between three and four hundred species are described, and it is not unlikely that nearly a thousand species will be found on the continent north of Mexico and the West Indies. The limits to which this work is confined are all of America north of Mexico and the West Indies, i.e., all north of the southern border of the United States, including British America, Arctic America, and Greenland, as the latter belongs to the same (circumpolar) fauna as Arctic America, while the insects of the Coast of Northern Labrador are in many cases identical with those of Greenland.
